XlsxWriter is a Python library using which one can perform multiple operations on excel files like creating, writing, arithmetic operations, and plotting graphs. Let’s see how to add a chartsheet to an excel sheet and plot a line chart on it, using real-time data. Charts are composed of at least one series of one or more data points. Series themselves are comprised of references to cell ranges. For plotting the charts on a chartsheet, firstly, create a chart object of a specific chart type(i.e Line chart, etc). After creating chart objects, insert data in it, and lastly, add that chart object to the chartsheet object.

Prerequisite: Create and Write on an excel sheet  

Code: Adding the chartsheet in an excel sheet. For creating a worksheet that only holds a chart we are using add_chartsheet() method of workbook object. 

Python3




# Python3 program for adding a chartsheet
# in an excel sheet using xlsxwriter
 
# we import xlsxwriter module
import xlsxwriter
 
# Workbook() takes one, non-optional, argument
# which is the filename that we want to create.
workbook = xlsxwriter.Workbook('chartsheet.xlsx')
 
# The workbook object is then used to add new
# worksheet via the add_worksheet() method.
worksheet = workbook.add_worksheet()
 
# create a worksheet that only holds a chart
# using add_chartsheet() method of workbook object.
chartsheet = workbook.add_chartsheet()
 
# Create a new Format object to formats cells
# in worksheets using add_format() method .
 
# here we create bold format object
bold = workbook.add_format({'bold': 1})
 
# Add the worksheet data that the charts will refer to.
headings = ['Number', 'Batch 1', 'Batch 2']
data = [
    [2, 3, 4, 5, 6, 7],
    [10, 40, 50, 20, 10, 50],
    [30, 60, 70, 50, 40, 30],
]
 
# Write a row of data starting from 'A1'
# with bold format .
worksheet.write_row('A1', headings, bold)
 
# Write a column of data starting from
# 'A2', 'B2', 'C2' respectively .
worksheet.write_column('A2', data[0])
worksheet.write_column('B2', data[1])
worksheet.write_column('C2', data[2])
 
 
# Create a chart object that can be added
# to a worksheet using add_chart() method.
 
# here we create a line chart object .
chart1 = workbook.add_chart({'type': 'line'})
 
# Add a data series to a chart
# using add_series method.
 
# Configure the first series.
# = Sheet1 !$A$1 is equivalent to ['Sheet1', 0, 0].
 
# note : spaces is not inserted in b / w
# = and Sheet1, Sheet1 and !
# if space is inserted it throws warning.
chart1.add_series({
    'name':       '= Sheet1 !$B$1',
    'categories': '= Sheet1 !$A$2:$A$7',
    'values':     '= Sheet1 !$B$2:$B$7', })
 
 
# Configure a second series.
# Note use of alternative syntax to define ranges.
# [sheetname, first_row, first_col, last_row, last_col].
chart1.add_series({
    'name':       ['Sheet1', 0, 2],
    'categories': ['Sheet1', 1, 0, 6, 0],
    'values':     ['Sheet1', 1, 2, 6, 2], })
 
# Add a chart title
chart1.set_title({'name': 'Results of sample analysis'})
 
# Add x-axis label
chart1.set_x_axis({'name': 'Test number'})
 
# Add y-axis label
chart1.set_y_axis({'name': 'Sample length (mm)'})
 
# Set an Excel chart style.
chart1.set_style(11)
 
# Add the chart to the chartsheet.
# chartsheet.set_chart(chart1)
chartsheet.insert_chart('B3', chart1)
 
# Display the chartsheet as the
# active sheet when the workbook is opened.
chartsheet.activate()
 
# Finally, close the Excel file
# via the close() method.
workbook.close()

Output:
